摘要
We are in the final stages of constructing a near-IR integral field spectrograph for use on the Gemini 8m telescopes. CIRPASS, as this instrument is known, will have a fibre-based 499 element integral field unit (IFU). Several sampling scales and fields of view will be available by interchanging the fore-optics that feed the IFU. CIRPASS operates in the wavelength range 0.9 - 1.8 microns and offers spectral resolutions from 3,000 to 26,000. Other features of CIRPASS are a special masking technique which removes the OH airglow well upstream of the detector and a multi-fibre feed for multi-object spectroscopy.
